Tracing Sub‐Monolayer Contamination on Wafer‐Scale 2D Materials
Advanced Functional Materials, EarlyView.Sub‐monolayer adventitious carbon contamination limits the performance and reproducibility of 2D material‐based devices. This study demonstrates scanning helium microscopy (SHeM) as a non‐destructive, ultra‐sensitive tool for wafer‐scale imaging of surface cleanliness.

On monochromatic paths and monochromatic cycles in edge coloured tournaments
Discrete Mathematics, 1996 The author gives various conditions sufficient to ensure that a tournament whose arcs are \(m\)-coloured has a node \(v\) such that for every other node \(x\) there is a monochromatic path from \(x\) to \(v\). One such condition is that each directed cycle of length at most four is quasi-monochromatic, i.e., with at most one exception its arcs all have

Contributions to Discrete Mathematics, 2012 We prove that any r-coloring of the edges of Km contains a monochromatic even cycle, where m=3r+1 if r is odd and m=3r if r is even. We also prove that Km−1 has an r-coloring without monochromatic even cycles.

Advanced Functional Materials, EarlyView.Overdoping high temperature superconductors, such as YBa2Cu3O7‐δ (YBCO), is expected to maxime the critical current density by optimising the condensation energy for a given defect landscape, providing new thrust for the development of fusion enabling coated conductors. Here, precise oxygen control is achieved via an electrochemical method allowing for

Red-blue clique partitions and (1-1)-transversals [PDF]
, 2015 Motivated by the problem of Gallai on $(1-1)$-transversals of $2$-intervals, it was proved by the authors in 1969 that if the edges of a complete graph $K$ are colored with red and blue (both colors can appear on an edge) so that there is no ...

American Journal of Neuroradiology, 2015 BACKGROUND AND PURPOSE: Dual-energy CT is not used routinely for evaluation of the head and neck, and there is no consensus on the optimal virtual monochromatic image energies for evaluating normal tissues or head and neck cancer.

Advanced Functional Materials, EarlyView.A fluorine‐rich acrylate monomer (PFHEA) was solvent‐free applied to NCM90 and thermally decomposed under Ar to convert residual lithium into LiF and form a pre‐built LiF/fluorinated amorphous carbon (LiF/FC) interphase. The LiF/FC layer suppresses NiO rock‐salt reconstruction and microcrack propagation, lowers interfacial resistance, and improves Li ...
